Deceleration of SS433 radio jets [PDF]

open access: yes, 2013
The mildly relativistic jets of SS\,433 are believed to inflate the surrounding supernova remnant W\,50 depositing in its expansion possibly more than 99% of their kinetic energy (\cite[1998]{Dub98}).

VLBA Imaging of NGC 4261: Symmetric Parsec-scale Jets and the Inner Accretion Region [PDF]

open access: yes, 1997
We observed the nuclear region of NGC 4261 (3C270) with the VLBA at two frequencies (1.6 and 8.4 GHz) simultaneously. We find that the position angle of the parsec-scale radio axis agrees, within the errors, with the position angle of the VLA-scale jet ...

Tracing the extreme interplay between radio jets and the ISM in IC 5063 [PDF]

open access: yes, 2013
We report the discovery with the Atacama Pathfinder EXperiment (APEX) of an outflow of molecular gas in the radio-loud Seyfert galaxy IC 5063 (z = 0.0110).

KILOPARSEC-SCALE JETS IN THREE RADIO-LOUD NARROW-LINE SEYFERT 1 GALAXIES [PDF]

open access: yes, 2015
We have discovered kiloparsec-scale extended radio emission in three narrow-line Seyfert 1 galaxies (NLS1s) in sub-arcsecond resolution 9 GHz images from the Karl G. Jansky Very Large Array.

A Chandra Survey of Quasar Jets: First Results

open access: yes, 2004
We present results from Chandra X-ray imaging and spectroscopy of a flux-limited sample of flat spectrum radio-emitting quasars with jet-like extended structure. Twelve of twenty quasar jets are detected in 5 ks ACIS-S exposures.

HORIZON-SCALE LEPTON ACCELERATION IN JETS: EXPLAINING THE COMPACT RADIO EMISSION IN M87 [PDF]

open access: yes, 2015
It has now become clear that the radio jet in the giant elliptical galaxy M87 must turn on very close to the black hole. This implies the efficient acceleration of leptons within the jet at scales much smaller than feasible by the typical dissipative ...

An Old Fogey’s History of Radio Jets

open access: yesGalaxies, 2017
This paper describes a personal view of the discovery of radio jets in celestial radio sources. The existence of narrow, collimated optical features in distant objects has been known about since the early 20th century; however, the advent of radio ...

A Unified Theory of Jetted Tidal Disruption Events: From Promptly Escaping Relativistic to Delayed Transrelativistic Jets

open access: yesThe Astrophysical Journal Letters, 2023
Only a tiny fraction ∼1% of stellar tidal disruption events (TDEs) generate powerful relativistic jets evidenced by luminous hard X-ray and radio emissions.

INVESTIGATING PARTICLE ACCELERATION IN PROTOSTELLAR JETS: THE TRIPLE RADIO CONTINUUM SOURCE IN SERPENS [PDF]

open access: yes, 2015
While most protostellar jets present free–free emission at radio wavelengths, synchrotron emission has also been proposed to be present in a handful of these objects.

Hunting Gamma-Ray-emitting FR0 Radio Galaxies in Wide-field Sky Surveys

open access: yesThe Astrophysical Journal, 2023
The latest entry in the jetted active galactic nuclei (AGN) family is the Fanaroff–Riley type 0 (FR0) radio galaxies. They share several observational characteristics, e.g., nuclear emission and host galaxy morphology, with FR I sources; however, they ...
